IMPROVED PILTERING- AND POURING-BO'I'TLE.

Thoschedule referred to in these Letters Patent and making part of the same- To all whom it may concern:

Be it known that I, V. M. Gmswom), of Peekskill, in the county of \Vestch'ester, and State of New Yorl r, have invented a new and useful Improvement in a'Combilled Filtering and Pouring-Bottle and I do hereby declare that the following is a full, clear, and exact description thercof,-which will enable others skilled in the.

. tered, and that such filtered liquidcan at the same time be, at will, pouredout of the bottle.

The invention consists in fitting an open tube through the stopper of a larger bottle. The liquid to be filtered is poured into the larger bottle, and is, before it can ascend in the tube, filtered, so as to be pure when in the tube. It can then be conveniently poured out through the upper end of the tube, without interfering with the filtering-process.

Photographers have especially been annoyed by having to use a filtering-bottle and a pouring-bottle for the collodion, and other chemicals, andto them this invention will be of great value.

A, in the drawing,represents a bottle, made of glass or other suitable material, of suitable size and shape.

It is provided with an annular stopple, B, made of cork, glass, or other material.

' Through the stopple B is fitted a tube, 0, made of glass or other suitable material, of such length that it will reach nearly to the bottom of the bottle, and project above the stopple B, as shown.

l The lower end of the tube 0 may be somewhat-ex: panded, as shown, to hold, in the expanded part, the filtering-material, indicated,

- Such filtering-material may, instead of being in the in the annular space that is between the tube and bottle,

in any other suitable manner.

The liquid is poured into the bottle, passes through the filtering-material, and rises in the tube to the same height at which it stands in the bottle. It can, when filtered, be poured through the mouth of the tube. Instead of this, the liquid may be poured into the tube,

drawn on. v

For volatile liquids, there n aya wedge-shaped groove be cut into the outside of the cork l) of the tube, to disliquids, I would prefer to connect the stopperl) with-the stopple B, by means of a tube, D, as shown, so that the pressure may be equalized in A and G, and the equilibrium be constantly retained.

I do not, however, iu the construction of my main invention, confine myself to the combination with the pipe 1), as that need only be used for highly-volatile material. I v

The stopple B may be left off, in case the tube 0 is large enough to fill the mouth of the bottle A.

Having thus described my invention,
